Array for processing materials
Materials (e.g., plant biomass, animal biomass, and municipal waste biomass) are processed to produce useful intermediates and products, such as energy, fuels, foods or materials. For example, systems equipment, and methods are described that can be used to treat feedstock materials, such as cellulosic and/or lignocellulosic materials, using an array of vaults.
1. A treatment operating unit, comprising:
a plurality of enclosure systems, each enclosure system including one or more vaults, and
within each vault, an irradiation device and a treatment conveyor, wherein a biomass material is treated in each vault utilizing the irradiation device and the treatment conveyor.
2. The operating unit of claim 1 , wherein the enclosure systems are arranged in rows.
3. The operating unit of claim 2 , wherein the rows extend in a first direction, and wherein each enclosure system comprises two or more vaults extending in a direction generally perpendicular to the first direction.
4. The operating unit of claim 3 , wherein the first and second vaults of each enclosure share a common wall.
5. The operating unit of claim 4 , wherein each first vault is configured to accept untreated biomass from a storage facility.
6. The operating unit of claim 5 , wherein the first vault of each enclosure system further encloses equipment configured to transfer treated biomass from the first vault to the second vault of the enclosure system.
7. The operating unit of claim 1 , wherein the irradiation device comprises an electron accelerator.
8. The operating unit of claim 1 , wherein the treatment conveyor comprises a vibratory conveyor.
9. A method for producing treated biomass materials, the method comprising;
partitioning a biomass material into a plurality of biomass material portions,
conveying the biomass material portions into a plurality of first vaults, each first vault accepting one of the biomass material portions,
treating the biomass material portions in the vaults,
conveying the biomass material portions out of the first vaults, and
combining the biomass material portions.
10. The method of claim 9 , wherein treating comprises a treatment method selected from the group consisting of dosing with ionizing radiation, sonication, oxidation, pyrolysis, steam explosion, chemical treatment, mechanical treatment, freeze grinding and combinations thereof.
11. The method of claim 10 , wherein dosing with ionizing radiation comprises irradiation with an electron beam.
12. The method of claim 10 , wherein within each first vault the biomass material is treated with a dose between about 10 and about 50 Mrad of ionizing radiation.
13. The method of claim 9 , wherein each conveying step comprises pneumatically conveying.
14. The method of claim 9 , further comprising conveying the biomass material with a vibratory convey or while treating the biomass material portions.
15. The method of claim 9 , further comprising continuously partitioning the biomass material, continuously conveying the biomass material portions into the first vaults, continuously treating the biomass material portions and continuously combining the biomass material portions, to continuously produce a treated biomass material.
16. The method of claim 9 , wherein the temperature of each biomass material portion does not exceed 150° C. during the treating step.
17. The method of claim 9 , further comprising cooling each biomass material portion after treating each biomass material portion.
18. The method of claim 17 , wherein cooling is with a screw cooler.
19. The method of claim 9 , further comprising, after conveying the biomass material portions out of the first vaults, conveying the biomass material portions to a plurality of second vaults, each second vault accepting one of the biomass material portions, treating the biomass material portions in the second vaults, conveying the biomass material portions out of the second vaults.
20. The method of claim 19 , wherein each first and second vaults share a common wall.
21. The method of claim 19 , further comprising cooling the biomass material portions between the first treating step and second treating step.
22. The method of claim 9 , wherein treating reduces or further reduces the recalcitrance of the biomass material.
23. The method of claim 9 , wherein the biomass material is a cellulosic or lignocellulosic material.
24. The method of claim 23 , wherein the cellulosic or lignocellulosic biomass is selected from the group consisting of paper, paper products, paper waste, paper pulp, pigmented papers, loaded papers, coated papers, filled papers, magazines, printed matter, printer paper, polycoated paper, card stock, cardboard, paperboard, cotton, wood, particle board, forestry wastes, sawdust, aspen wood, wood chips, grasses, switchgrass, miscanthus , cord grass, reed canary grass, grain residues, rice hulls, oat hulls, wheat chaff, harley hulls, agricultural waste, silage, canola straw, wheat straw, barley straw, oat straw, rice straw, jute, hemp, flax, bamboo, sisal, abaca, com cobs, com stover, soybean stover, com fiber, alfalfa, hay, coconut hair, sugar processing residues, bagasse, beet pulp, agave bagasse, algae, seaweed, manure, sewage, arracacha, buckwheat, banana, barley, cassava, kudzu, ocra, sago, sorghum, potato, sweet potato, taro, yams, beans, favas, lentils, peas, and mixtures of any of these.
25. The method of claim 9 , wherein the treated biomass material is produced at a rate of at least 500 lb/hr per vault.
